Installing hole sidewall 21e, 21f have the retainer function of blocking left and right sides work feed tooth platform 23,24.
As Fig. 2～shown in Figure 6, the tooth portion both end sides of left and right sides work feed tooth 27,28 is fixed on each maintaining part 27b, 28b.Therefore, it has the rigidity that can resist from top loading load-bearing.So during work feed, even from top the work feed tooth is applied big load, the work feed tooth can be not crooked yet, so can keep the craspedodrome of cloth.Then, device under the state that assembling has finished, make maintaining part 27b, the 28b of left and right sides work feed tooth have certain clearance each other, overlap ground (stack shape) configuration simultaneously.In addition, the reinforcement ribs 27ba that protrudes to left end side from maintaining part 27b protrude to be set, setting is from the handle part 28b reinforcement of distolateral protrusion ribs 28ba to the right.Therefore, the side view of maintaining part is L font and the font of falling L.
As mentioned above, because maintaining part 27b, 28b not wearing and tearing to each other, so, in the life-span that can improve device, simultaneously,, can improve its rigidity again so neither occupy the space owing to be provided with ribs.
The action of embodiment 1 now is described.
At first, drive Sewing machines, then cloth pushing shaft 30 rotates up and down, utilizes feed eccentric 32 up and down, bestows the motion of above-below direction by 33 pairs of cloth pushing tables 20 of work feed connecting rod up and down.Simultaneously, do not make horizontal cloth pushing shaft 31 rotate (shaking), utilize the rotation of this horizontal cloth pushing shaft 31 to bestow the motion of horizontal direction by 36 pairs of cloth pushing tables 20 of horizontal work feed arm by there being illustrated horizontal work feed driving mechanism.By the motion of these cloth pushing table 20 above-below directions and the motion of horizontal direction, left and right sides work feed tooth 27,28 carries out and the same in the past cubic work feed motion.
In this embodiment, eccentric cam 40 rotates because of the rotation of cloth pushing shaft 30 up and down.Therefore, by left and right sides work feed connecting rod 41 and interlock body 42, axle 43 is that the center is shaken with horizontal cloth pushing shaft 31.Then, by the slotted hole 44c of last lower body 44, axle 43 motion only pass on axle 43 above-below direction motion and lower body 44 is moved up and down.At this moment, support with cannelure 22a and guiding parts 50 and to go up lower body 44 and move freely at above-below direction only, so its reciprocating motion sleekly along the vertical direction.
When the ascending amount of last lower body 44 was bigger than the ascending amount of cloth pushing table 20, by axle 47, left and right sides work feed tooth connecting rod 45,46 and left and right sides work feed tooth 23,24, left and right sides work feed tooth 27,28 moved to the direction of separating with pin respectively, plays the effect that Bradley is stretched.And each back shaft 29a, the 29b that are fixed on the left and right sides work feed tooth platform 23,24 are supported among supported hole 21c, the 21d that forms on the cloth pushing table slidably.Simultaneously, sliding part 23a, the 24a of left and right sides work feed tooth platform are supported in the gathering sill 26 slidably.Therefore, left and right sides work feed tooth 23,24 is just done to separate along glide direction Y sleekly and is moved.
When the slippage of last lower body 44 was bigger than the slippage of cloth pushing table 20, by axle 47, left and right sides work feed tooth connecting rod 45,46 and left and right sides work feed tooth platform 23,24, left and right sides work feed tooth 27,28 was done near moving along glide direction to the direction near pin respectively.
The motion of the glide direction of left and right sides work feed tooth 27,28 is set at; Briefly, (with left and right sides work feed tooth 27,28 when cloth feeding direction begins work feed) beginning is to the motion of leaving the pin direction when needle point is pulled out from cloth, and when acupuncture during to cloth (when stopping) beginning with left and right sides work feed tooth 27,28 work feeds move to direction near pin.This uses with respect to the setting angle of the eccentric cam 40 of cloth pushing shaft 30 up and down and sets.So, the moving along glide direction Y of work feed tooth 27,28 about during work feed with regard to move resultant motion with horizontal motion of the above-below direction that becomes left and right sides work feed tooth 27,28, cloth is subjected to the active force to pin left and right sides detaching direction, transverse stretching and meanwhile to the place ahead of cloth feeding direction X work feed.Therefore, upward use the cloth-feeding device of first embodiment hardly fold can take place at the sawtooth stitch sewing machine that pleat (being called fold) takes place easily and decoration stitch sewing machine etc.
